AnAlysisduring the winter, the liv-ing room, Foyer and ga-rage receive sun at 9 am, while the dining Room, Kitchen and Family Room are darkest. this is al-most optimal; with the exception of the kitchen, all rooms important to morning routines are lit. at noon, almost no rooms are lit well with the excep-tion of the living room. however, no-one is home at noon, so this is not a problem. at 3pm the din-ing Room, Kitchen, Family and laundry rooms are all well-lit while the living Room, office, and garage are not. this is optimal because family members return home from school or work after 3pm and need light in the dining Room, Kitchen , Family and laundry Rooms.

3pmAnAlysisoverall, the winter analy-sis is very coals to the summer analysis. all the same rooms receive sun at the same times of day, but the sun is lower in the sky and thus less intense. summer light is much stronger and therefore warmer. nevertheless, all rooms generally receive sun when it is beneficial (except at noon, when almost no sun is perceiv-able from indoors).

AnAlysisBecause the site is orient-ed with a south-east dom-inated slope, all water moves around the house in the manner illustrated here. the topography and current swale already works well to divert water away from the house.

AnAlysisi would not recommend a redesign of the house. during the sum-mer and winter, we rarely use the a/C and heating respectively. the heat from the kitchen dissipates through the rest of the house due to its central location, and all rooms receive sun when needed, for the most part, year round. the wind comes strongly from the west year-round. thus, the garage and attic crawl spaces are located on the northeast and effectively block most wind. what is not blocked is broken up by strategically placed trees. although the shadows of the neighboring houses and the line of trees that separate the house from the farmland behind it come close, they never actually reach the house. only in winter after 3pm does the shadow of the large line of trees come into contact with the house itself. on average, the house is very comfortable and solar orientation, heating, and views are not a problem. the skylights in the Kitchen and upstairs master bath-room (at a 25 degree angle from horizontal, facing the southwest) capture sun nicely during the winter and avoid it during the summer. the house rests atop a hill and thus has an excellent view of the en-tire lehigh valley on the northeast, southwest and southwest sides. all rooms face these orientations already; the master bedroom faces southwest, Bedroom 1 faces southwest, and bedroom 2 is the excep-tion. while Bedroom 2 does not have a view of the valley, it has a beautiful view of the farmland behind the property. although the house is a cookie-cutter, the contractors and architects who designed it seemingly knew what they were doing (or perhaps got lucky) from an orientation standpoint, at least.

CURRenT HeATinG And CooLinG CosTs PeR YeAR: $1,060 With the installation of RiteTemp 7 Day Programmable Thermostat Energy Star Compliant :setback thermostats riase the point at which air conditioning turns on and lowers the point at which the heat turns on. this saves energy in both the summer and winter and thus saves money.

Cost of thermostats: 2 @ $39.93 = $79.86

Reduce Heating Set Point to an average of 62ºF:

Current@ 65ºF = 240.9 mmBtuReduced to an average of 62ºF = 230.8 mmBtu

240.9 - 230.8 = 10.1 mmBtu * $13.1 per mmBtu = $132.11 annual savings

Increase Cooling Set Point to 69ºF:

Current @ 65ºF = 2578.4 kwh increased to an average of 68ºF = 2464.7 kwh

2578.4 kwh - 2428.9 kwh = 149.5 kwh * $0.106 per kwh = $15.85 annual savings
